SI.com: Edwin Jackson, Rick Porcello among biggest surprises

There have been a lot of surprises this year in Major League Baseball (Raul Ibanez's success and David Ortiz's struggles near the top of the list) and two members of the Detroit Tigers pitching staff are on the list of "positive" surprises according to Sports Illustrated's Jon Heyman.

June 12, SI.com: 7. Edwin Jackson, Tigers SP. Getting a starter for backup outfielder Matt Joyce was a great pickup for Tigers GM Dave Dombrowski. Jackson's been strong -- he hit 99 on the gun in the ninth inning of a recent start -- though pitching in Comerica Park probably hasn't hurt.

13. Rick Porcello, Tigers SP. Porcello has tremendous talent, but starting 6-4 with a 3.98 ERA at age 20 is simply amazing.
